What an insane 24hrs of sweaty coding at the @starkware hackathon with the giga brains @rvorias @wraitii @sylvechv @0xbellemere

The sheer amount of innovation in one room in 24hrs was mind-blowing 🧠

Recap of why we built the session key
@Briq @LootRealms @topology_gg

#devconnect for me has been about on-chain gaming (no surprise) however, we are *early* (not a meme).

On-chain gaming is the intersection of economics, game theory, and technology. But the current UX is clunky as players have to sign every transaction.

With dapps that require infrequent transactions, this is fine UX.

But the dream is near-RTS gaming on-chain with a high frequency of transactions. The UX breaks if they must sign multiple transactions a minute.

But there is a solution: Ephemeral session keys

By creating a one-time signing key stored in the browser a user only has to sign once during a game session.

This removes the need for the player to sign repeat transactions.

If solved correctly this is a 100x UX improvement that every on-chain game will implement.

So together the @LootRealms @briqNFT @topology_gg hacked together the world's first plant2earn "Starkdew Valley".

A simple plant than harvest game that requires the frequent signing of transactions.

The player sows seeds which then grow into plants and are harvestable after 20 seconds

The plant state is stored on-chain:
- Time planted
- X coordinate
- Y coordinate

and yes, the game is just harvesting plants. This is what the players really want...

In the demo, we showed the UX difference between a session key and no session key.

Before session key: the user must sign the planting of every seed.

After session key: the user only signs one transaction per session.

The idea for session keys is not really new, but with #StarkNet account abstraction feature it is possible to create complex session key contracts with specific permissions per dapp.

Potential features:
- Spend limit
- Function call restriction
- Multisig integration

What's next?
Native integration into @argentHQ to enable on-chain games to fully utilize this feature and onboard the next cohort of gamers.

At @LootRealms we will be implementing a version of a session key in our upcoming Settling game running on StarkNet using @argentHQ

It was an honor to hack alongside the other 160 hackathon participants some truly amazing minds that we will all be exposed to over the coming months and years.
